Application inea Januaryl s, 132e.l sei-iai No. 80,024.

This invention relates to orifice mixers,

and particularly to orifice mixers. suitable' troleum rening operations, in which it is"` necessary to treat the oil with relatively small amounts of non-miscible reagents sucfi as sulphuric acid, water, alkalis, sodium plumbite solution and the like.

The invention willreadily be understood from the following description of a pre'- ferred embodiment which is illustrated in the accompanying drawing in which: f

Figure l'is alongitudin'al section of the apparatus, on the broken' lineA 1-1 of Fig. 2; an v ken line 2-2 of Fig. 1.

In the embodiment shown in the drawing, 1 isa pipe provided withl an outer flange 2 for connection with a liquid sup l line, for

example, an oil supply pipe-3. immiscible reagent may the. pipe 4 or in other suitable manner. The

other end of the pipe 1 is closed by a4 plate '5. Adjacent the flange'2, a flange 6 is attached to the pipel by welding orin other suitable manner.. Between the closed end 5 and the flange 6, the walls of thepipe 1 are provided with a large number of orifices 7. Arranged around pipe 1 and in spacedrelation thereto lis a second pipe 8 having a closed en d 9 and a flange 10 at its other end which'is removably attached tothe flange 6,

or example, by bolts 11, a suitable gasket- I 12 being interposed lbetween the two flanges.

Adjacent the flange 10, the -pipe 8 is provided with a flange 13 attached to pipe 8,

for example, by welding, and between the end 9 `and flange 13, the pipe A8 is provided with a large number of orifices 14. .Ar-

. The flanges 2 and 20 are ranged about the pipe 8 and in spaced relation thereto is located anouter casing 15, provided at one end with a flange 16- which is removably attached to the flange 13, for example, by bolts 17, a suitable gasket 18 bein interposed between the flanges. Be-

yon the ipe 8, the outer casing 15 is referably re uced orl tapered as at 19 an the reduced end provided with a flange 20. The i flange 20 may be connected with a pipe 21.

preferably standard pipe flanges so that t 'e mixer may be inserted with ease in a linev conveying the e supplied to the o il by A termingling liquid such as oil is beingr treated with a r liquids to be mixed. The orificesl7 and 14 'in the pipes 1 and 8 are preferably arrangedthe individual orifices 14 are preferablyA staggered c ircumferentially of the pipe 8 `with respect to the individual orifices 7v of the pipe 1, as will readily be understood from Fig. 2, so that the flow ofthe liquids 'from' the orifices 7 to the orifices 14'combines longitudinal and circumferential flow. While I have shown two perforate'dpipes 1 and 8, it is to be understood that a greater number may be used if desired. Fig. 2 is a transverse section on the bro- -the liq'uids to` be mixed may be introduced into the pipe 21 and may be supplied to pipe 3, if desired. Such operation is, however,-

not preferred. Ihepassage'through the orifices 7 and 1 4, the 1 tortuous ath of the liquids andV the turbulent ow thereof.

through the apparatus result in thorough ino the liquids and where a e atively small uantity of immiscible reagents such as su phuricacid, water or the like, said reagent is broken up into minute globules so thatits action on the oil or the like is rendered moi'euniform and effective.

The improved mixer possesses the valuable characteristic that it can easily be taken apart and cleaned. By removing bolts 11 and 17 the closed pipes 1 and 8 and outer casing 15 are se arated and may be.easily cleaned both wit vin and without. In operating in the preferred manner, with the flow -in the direction indicated by the arrow in Fig'. 1, the device does not accumulate de? -position of sludge, and is substantially self cleaning.

While I have described onepreferred-embodiment of the' invention, it is to be under- I various modifications may stood that I amn'ot nailed ther-eraan@ readily be made therein, within the Scope of the appended outer casing provided with liquid 7conduit means and means uniting said outer easing with the flange near the end of the outermost tube so as to substantially enclose said outermost tube in said casing.

2. A liquid mixer comprising a tube provided witli a flange and closed at an end, said tube being` provided with a large number o orifices betweenl said flange and closed end, a larger tube provided with a flange at one end and with a flange near said end and closed at the other end and provided with a lar-ge number of orifices between said closed end-and the flange near the open end, removable means for connecting the flangefat the end of the second tube with the flange of f another so that the Within the former, an outer casingi tially 'provided With liquid conduit means, and

the first tube so that the second tube encloses .the first tube in spaced relation, an outer casing and removable means connecting the other' flange ofthe second tube tothe outer casing.

'3. A liquid mixer comprising a plurality of perforated tubes of different sizes, ta flange at'the end of eachtube, a flange near the end of eac-h tube larger than the flange Vat the end of the tube,l and bolts uniting a flangeat'the end of one tube with the flange near the end of another so that the latter tube lies substantially Within the former.

4. A liquid mixer comprising a pluralityof perforated tubes of different sizes, a flange at the end` of each tube, of each tube larger than the flange at the end of the tube, bolts uniting a flange at the end of one tube With the flange near the end of latter tube lies substanbolts uniting said outer casing with the flange near the end of the outermost tube so as -to substantially enclose said outermost tube in said casinv;
